IMPROVEMENT vIn PuMPs.

Y The Schedule referred to in these Letters Patent and making part of the same.l

I I, THOMAS J. LAPSLEY, of the city of Nashville, county ot" Davidson and State of Tennessee, have invented a certain new and. useful Improvement in a Pump for Raising Water, of which the following is a ing.' To the lower end of thisplung'er a small ang'e is screwed with a hollow sleeve on the top and also on the underside-that on the top being perforated `with holes-,near the ange, and made of a 'size to cor respond with the end ot' the plunger, to which it is screwed, but that on the under side being. slightly larger,.and becomes the female to the sleeve of another similar il. nge which is screwed into it, and when so arranged forms a hollow piston-head or valve-chamber to the upper valve, which valve, both above and below, consists in a perfectly round India-rubber ball, one ol' which works ou a seat in the-flange at the bottom of the plunger the sleeve or chamber around which is perforated with holes for the water to pass through, and in order to pack the pistou-head it is provided with a metallic ring fitted between the Bauges of the head similar to that of the steam-engine, but with grooves in the side, and cut in two diagonally across the side in order to permitit `to expand.

Between this packing-ringand the piston-head is a valve lof `this pump is situated in theflange at the bottom of the chamber, and has a chamber or sleeve raised around it perforated with holes, and a pin through it to prevent .the valve from getting out of place.

4 This pump is also provided with an air-vessel on the discharge-pipe, which pipe can lbe changedfrom one side to the other when required, for convenience in its operation, which may be done either by hand or by other power, its operation being simply that of the ordinary pump, which raises the water above the lower valve, and 'as the plunger returns the water is forced up through the holes in the pistou-head against the packing, and afterward through the holes in the plunger above the head into the chamber, and out at the discharge-pipe above.

Having thus fully described the nature of my invent-ion, a more .perfect understanding of which may be had byreference to the drawing@ `Figure 1 is a sectional view, showing the internal arrangement of the pump complete.

Figure 2 is a side elevation, with one side left out in order to show the piston-head and the dischargeholcsju the valvechambe'rs.

And "in order that they may he more fully understood, I will proceed to describe Athem by reference to theletters marked thereonin which A is the pump-chamber.

Bis the plunger.

G is the flange-sleeve on the ent T are the holes in this sleeve.

R R are the flanges of the pistonhead.

D is'the valve-chamber in the head.v

E are the discharge-holes againstthc packing.

J is the packing.

H and H' are the rubber valves.

I and V are the seats. y

L is the air-chamber in the'plunger.

K is the receiving-pipe.

N N are the discharge-pipes.

M is the packing-box.

` O is the lever-stand.

P is the lever.

n Q are the links, connecting it with the plunger.

Having thus fully described the drawing,

What I claim as new, and desire to secure by Lett'ers Patent, is

l. The colnbinationof the plunger B with' its airchamber L and holes U, the sleeve O with its dischargeholes T, the piston flanges R lt with the packing .T J, the valve-chamber Dwith'its discharge-holes E, the valve H and pin G, by which it is held in place, substantially as and for the purpose hereinbefore set forth.

2. The combination of the lower valve-chamber E with its discharge-holes y, the valve H', the seat V, and receiving-pipe K, the. chamber A with its discharge-pipesN N, and stand O, the lever Rand-link Q, which connects it with thc plunger, substantially as and for the purpose hereinbefore set forth.
